WIND CHEST AND VALVE ACTION FOR ORGANS.

Specification of Letters Patent.

Patented June 13, 1922.

Application filed January 10, 1921. Serial No. 436,064.

T 0 aZZ whom it may concern:

Be it known that 1, JAMES Torr, a citizen of the United States, residing at Chicago, in th county of Cool; and State of illinois, have invented certain new and useful Improvements in l 'i ind Chest and Valve Actions for Organs, of which the following is a specification.

My invention relates to an organ, more particularly to the valve action thereof and its associated parts and. the object thereof is to malre the valve action including its seat, as a unit and also to make such unit readily removable with the result that the entire valve action may be removed without opening or disturbing the wind-chest. My unit structure is also so made as to be capable of supporting the organ pipes, thereby dispensing with the usual supporting racks. Other novel and advantageous features of. construction in my new organ structure will be apparent from the description. hereinafter given.

In the drawing Fig. 1 is a sectional elevation of part of an organ embodying my invention. I Fig. 2 a top plan view of one of my units inserted inthe wind-chest. Fig. 3 a section on the line 3-3 of Fig. 2 but on a larger scale. Fig. 4: an elevation partly in section of my unit: Fig. 5 a detailed view illustrating my unit in connection with one of the larger pipes; Fig. 6 a detailed view similar to Fig. 2 illustrating a modified form or construction oil contact plates; and Fig. 7 a section on the line 7-'7 of Fig. 6.

Referring to the particular embodiment of my invention herein selected for illustration and description, the wind-chest is of the usual construction. and provided with the wind-trunk or inlet 2 and with a top board 3 having series of top openings t in vertical line with the series of organ pipes such as the larger pipes 5 and the smaller pipes 6.

The valve action including this seat is made as a unit the same also serving to support the organ pipes, thereby dispensing with the usual racks especially for the smaller pipes. Each unit is made of such character and size as to be readily insertable into and removable from its hole 4: in the top board of the wind-chest, in which operation the organ pipe may be first removed from the unit or removed therewith as desired. Moreover, the units of each series are separate physically even as to the electric wiring so that any one unit of a series is independently insertable in the windchest and independently removable therefrom.

Describing the unit structure illustrated,

the same includes a head portion 7 which may be termed the pipe block, whose central body portion enters and substantiallyfills the opening 4t and has an intermediate flange portion 8 resting upon the top board through the medium of the sealing ring 9 so as to hold thebloch in its inserted position and to seal said opening. This block is provided with a central passage or windway 10 whose upper portion is enlarged. and also tapered so as to receive the lower end of the pipes such as the smaller pipes 6 in Fig. 3 and the larger pipes 5 as in Fig. 5. The lower surface of the block adj acent the wind-way 10 forms a seat 11 for a vertically operating .valve 12 which in the present instance is controlled and operated pneumatically. This valve is connected to and supported by a diaphragm structure including a top diaphragm 13 and a lower dia phragm l l connected together attheir margins by a ring 15. The lower diaphragm is in turn connected to a ring which is secured to a plate or block 17 constituting a diaphragm support. This support 17 is provided with a chamber 18 communicating with the interior of the diaphragm struc ture and also with a passage 19 and a cham her 20 in a plate or packing-'21 which is in,-

terposed between the plate 17 and a magnet block cated draw 22. A coiled spring 23 which is lo- 1n the chamber 18 normally tends to the valve '12 from its seat against the pressure ol the air in the diaphragm struc- I ture. In the chamber 20 there is located the vertically operating armature 94; con trolled by the electro magnet 25 which is secured to and supported by the block 22.

This armature controls the lower end of an exhaust passage 26 which extends through the plate 17 and through the short pipeQT passing through the dowel post 28 and thence passing through the pipe block and to atmosphere at 29. The tube 27 is preferably employed to provide for sealing of the exhaust passage as it runs from the plate 17 to the pipe block 7 The parts described are removably held or clamped together in suitable manner and in the present instance I utilize brass bolts 30 which serve also as electrical conductors or Cir eral return through expensive job.

such structure is rotated binding posts for the wires 31 ot' the magnet and as means for securing electrical contacts 32 upon the tops ot' the units. These bolts pass through the blocks and plates 7, 17, 21 and 29 and also tl'n-ough dowel posts 33 similar to the post 28 which posts are all located. between the block 7 and. the plate 17. Thus these bolts together with the nuts 34 constitute clamping means and also the necessaiy electrical connections for the magnets 25. The contacts 32 are normally in contact with the contacts 35 and 36 secured to the top board by the screws 37. The contact 35 is electrically connected to the genthe wire 38 and the contact 36 is electrically connected to the usual key contact corresponding to this unit by the wire 39.

Describing the valve action; when the hey contact is made and the magnet is energized the armature 2-1: is attracted against the air pressure in chamber 20 tending to hold it in its upper position, whereupon the exhaust passage 26 is open to atmosphere and the air pressure in the diaphragm struc ure is permitted to escape. As a result, the valve 12 is witl'idrawn from its seat 11 and the air from the wind-chest is admitted to the organ pipe. In the event that it is necessary to repair or examine any valve action, the organ pipe is first removed or not, as desired, and the entire unit including the valve action and its seat is slightly turned and then withdrawn upwardly t'rom the windchest and removed theretrom. The entire structure including the valve seat and valve wherein the trouble generally resides is accessible and under the observation of a repairman. As a result, the valve action can be properly repaired and test d for proper action before it is again inserted in place. Not only this, but this operation does not require the opening or dismantling of the wind-chest which is alv-iays a laborious and liloreover, I am. enabled to repair any one or more of the valve actions and associated parts without putting the organ out of commission.

In the act ot' removal ot'thc unit structure slightly so as to carry the contacts 32 out 0t their locking engagement with the contacts and 36, the latter being otlset upwardly at their inner ends as indicated in Fig. i. The structure is new tree to be lifted upwardly out of the top opening of the wind chest and to be removed bodily therefrom. In the act of in serting the structure in place such structure after being inserted into the opening is rotated or moved angularly so as to bring its contacts 32 into engagement with the contacts 35 and. 36. These contacts theretore serve both as electric contacts and as means for holding the unit structure in position.

The double opposed diaphragms 1.3 and 1-;larc very advatntagcous in practice t'or several reasons, particularly l. ccausc, in view of the fact that their margins are not an chorcd but Freely float, the diaphragms (one oi which is anchored at its middle portion and the other of which is secured to the valve) have considerable mo'vt-uncnt and flexibility, thereby assuring perfect seating of the valve and also because the valve is given a greater range or movement.

In Fig. 6 I. have shown a modified form of construction of contacts according to which the contacts -10 are made somewhat ditli'erent in shape as con'iliiared with the contacts 35 and 3 artici.ilarl v in that they are provided with stop flanges all which limit the angular movement; of the unit structure when being inserted. in place. As shown in detail in. Fig. 7, the cont: ts may also be provided with locking socket and hTHOlJ indicated. at 4-2 and 4:? whereby they may be held yieldingly in engaged position.
